I tried to play the demo but it said that my account couldn't be connected to the master machine or something like that
That's strange - I'll try downloading myself to see if there are problems.
Thank you so much for the report! I had indeed destroyed account creation, but it's fixed now. Would you mind trying again? You don't need to redownload, since it's a server fix.
It is working now. I'll definitely play and stream this on Sunday or Monday :)
Awesome thanks :)
